Abstract

Se proporciona un método para transmitir contenidos de medios de un dispositivo receptor de contenido de medios tal como un decodificador hacia uno o más dispositivos de usuario que cuenten con la capacidad de despliegue, almacenar o dar salida al contenido de medios. El método incluye la recepción de, en el decodificador, contenido de medios codificado de acuerdo con un formato particular, incorporar en el contenido de medios, mientras que se codifica de acuerdo con un formato particular, una marca de agua que contiene los datos que identifican el codificador y entonces transmitir el contenido de medios con marca de agua hacia uno o más dispositivos de usuario. La codificación de una marca de agua mientras que el contenido es codificado de acuerdo con el formato recibido permite que sea agregada una protección y el contenido sea transferido hacia otros dispositivos sin tener que decodificar el primer contenido. El método se puede implementar mediante un dispositivo de recepción de contenido de medios apropiado con la ejecución de un programa de computadora. Se proporciona un aparato correspondiente para implementar el método.
